Network Cable BlueOptics FN-CABLE-QSFP+50CM QSFP DAC 56G 50cm Blue

The BlueOptics FN-CABLE-QSFP+50CM QSFP DAC 56G 50cm Blue is a direct attach copper (DAC) cable engineered for short-range, high-bandwidth interconnections in networking equipment. With QSFP+ style QSFP connectors on both ends and a 50 cm length, this cable supports 56G aggregated data rates suitable for top-of-rack switches, servers and network interface cards. Its compact form and plug-and-play design enable straightforward installation in dense rack environments where low latency and reliable electrical signal integrity are required.

Advantages

This BlueOptics cable offers a compact 50 cm reach that reduces signal loss and latency compared with longer copper runs. The QSFP-compatible connectors provide broad interoperability with devices that accept QSFP+ style DACs, and the cable supports aggregate 56G data signaling for high-throughput links. The blue sheath gives easy visual identification in cabling bundles while the robust construction and strain relief improve mechanical durability for repeated insertion cycles.

Suitable for

• Short-reach connections between switches and servers in data centers
• Top-of-rack and end-of-row networking installations
• High-throughput links in compute clusters and storage arrays
• Testing and lab environments requiring low-latency copper interconnects

Key specifications

• Connector type: QSFP-style on both ends
• Cable type: Direct attach copper (DAC)
• Maximum aggregated data rate: 56 Gbps
• Length: 50 cm
• Color: Blue outer sheath for identification
• Form factor: Low-profile QSFP module style for high-density ports

How to use

Install the cable by aligning each QSFP connector with the corresponding QSFP port and inserting until the connector latches. Ensure both ends are fully seated to maintain electrical contact and signal integrity. The 50 cm length is intended for short interconnects inside racks; avoid stretching the cable beyond its natural length and route it to prevent sharp bends. No additional drivers are required for typical QSFP-capable network equipment; the link should be detected automatically once both ends are connected and devices are configured for the desired link speed.

Usage recommendations

For optimal performance, use this DAC cable for short, high-speed links in data center environments and ensure ports are configured for 56G-capable operation. Keep the cable free from tight bends and limit mechanical stress near the connector boots. Verify compatibility with your switch or server vendor’s QSFP+ port specifications before deployment.
